To solve equations, you want to isolate the X. So, the first step will be to distribute that 4 into the 2x + 1.
4 x 2 = 8
4 x 1 = 4 So we have 4(2x+1) = 8x+4. When we plug this into the equation, that gets us 8x + 4 - 2x = -8. Next, let's combine like terms now that we've distributed everything out. 8x - 2x = 6x. Now we have
6x + 4 = -8. Next, we subtract 4 from both sides to isolate the X; 6x = -8 - 4. -8 - 4 = -12. So now we have 6x = -12. The final step to isolating the X is to divide both sides by 6; 6/6 = 1, and -12/6 = -2. Our final answer is X = -2.

The correct answer is: [B]: "40 yd² " .

First, find the area of the triangle:
The formula of the area of a triangle, "A":
A = (1/2) * b * h ;
in which: " A = area (in units 'squared') ; in our case, " yd² " ;
" b = base length" = 6 yd.
" h = perpendicular height" = "(4 yd + 4 yd)" = 8 yd.
___________________________________________________
→ A = (1/2) * b * h = (1/2) * (6 yd) * (8 yd) = (1/2) * (6) * (8) * (yd²) ;
= " 24 yd² " .

Now, find the area, "A", of the square:
The formula for the area, "A" of a square:
A = s² ;
in which: "A = area (in "units squared") ; in our case, " yd² " ;
"s = side length (since a 'square' has all FOUR (4) equal side lengths);
A = s² = (4 yd)² = 4² * yd² = "16 yd² "

Now, we add the areas of BOTH the triangle AND the square:
_________________________________________________
→ " 24 yd² + 16 yd² " ;
to get: " 40 yd² " ; which is: Answer choice: [B]: " 40 yd² " .

Answer: Undefined
Step-by-step explanation:
Slope=rise/run
For vertical lines, there is no "run" so the bottom of the slope fraction would be 0. Dividing anything by 0 is always undefined.
